Apparently Dick Cheney (one our former Veeps and President of the Senate) fearing for his life, decided to terminate the in-built wireless capabilities of his lifeline. In this case, none other than his implanted heart defibrillator.
We are bound to discover more of this behavior going forward given the paucity of medical device security, and the need to access telemetry from these life giving, and sustaining machines, without invasive measures.
2014/11/07: As an addendum to this post, it behooves me to add I have great respect for Mr. Cheney. His efforts to control his own destiny, medically and otherwise, are exceedingly admirable.
